Joint brace adjustable device

Abstract

The present invention discloses a pivotal disc is pivotally coupled to a first brace and a second brace. The pivotal disc has a motion-limit member and a positioning member limiting the angle by which the second brace rotates with respect to the first brace with the pivotal disc being the axis and fixing the angle between the first and second braces. The present invention is characterized in that the motion-limit member uses a range-adjust member to push a slide block and determine the range that a block portion of the second brace is blocked by the slide block, and that the positioning member uses a switch knob actuates on end of a positioning rod to engage with or depart from a positioning notch on the pivotal disc, and that the pivotal disc has two limit elements to define the maximum movement range of the first brace and the second brace.

Description

FIELD OF THE INVENTIONThe present invention relates to a joint brace adjustable device, particularly to a device to fix the angle of a joint or limit the movement of a joint.BACKGROUND OF THE INVENTIONJoints are the pivots of our bodies, whereby we can perform various movements. Among them, the knee joints and the elbow joints are more heavily burdened and more likely to be hurt.Thus, there are various joint braces invented. The joint braces may be categorized into the prophylactic braces preventing from joint hurts, the functional braces limiting joint movements after surgery, and the rehabilitative braces fixing the angle of a joint during rehabilitation. The abovementioned joint braces respectively have different structures to implement different functions. There are also multi-functional joint braces. For example, a Taiwan patent No. M311408 disclosed an “Adjusting Device for Knee Joint Fixer (1)”, wherein the slide way thereof has insert slots, and two position-limiting blocks ...

AI Technical Summary

Benefits of technology

"The present invention provides a joint brace adjustable device that simplifies the structure, reduces cost, and allows for easy adjustment of the joint angle and movement range. The device includes a pivotal disc with a motion-limit member and a positioning slot, and a range-adjust member that can be rotated to change the angle between the braces. The device also includes an elastic element and a slide block to move the braces to different positions. The positioning member has a positioning rod and a switch knob to engage or disengage with the positioning notch. The device can be easily operated and has a simple structure, making it more adaptable for different joint angles and movements."

Problems solved by technology

Among them, the knee joints and the elbow joints are more heavily burdened and more likely to be hurt.

However, the structure is too complicated, and the operation process thereof is too troublesome.

The application thereof is only using the engaging element to fix the position of the second plate, but the cost thereof increases because the structure becomes further complicated.
